Abstract
The utility model discloses a pneumatic air-hood, in particular to an anti-wind and anti-rain air-hood used for an outlet of a vertical exhausting duct of a kitchen or a toilet of civil buildings. The utility model not only can defend wind and rain but also can result in a negative pressure in a flue in virtue of the pneumatic force to form the self-absorbing effect. The pneumatic air-hood mainly consists of a base, cross-shaped fan blades, worm wheel vanes, a top cover and a shaft. The worm wheel vanes are a series of arc-shaped strip slices which are roundly arranged between the top cover and the cross-shaped fan blades to form a windmill vanes distribution, resembling either a drum or a windmill on appearance. As gaps are arranged between vanes, air from any direction can drive the worm wheel vanes to turn to drive the cross-shaped fan blades to turn so as to form the self-absorbing capability. The utility model also can be used for outlets of other vertical exhausting ducts and flues and so on.
Description
One. technical field:
The utility model belongs to a kind of vertical row ducting outlet with preventing that blast cap, especially lavatory, civil buildings kitchen vertical row ducting outlet are with preventing blast cap.
Two. background technology:
In order to protect urban environment, to reduce and pollute, help the people's physical and mental health, No. 295 literary compositions that nation-building portion issued in 1999 require: lavatory, newly-built dwelling house kitchen must be provided with the vertical out-fall system.Here said vertical out-fall system generally is made up of air channel, check (non-return) valve, fume exhauster, roof blast cap four parts.At present, lavatory, kitchen flue gas emission atlas has all been worked out in each province and city, and its Apoplexy cap is generally prefabricated board rain proof type, PVC plate wind-proof type, and for example ZPS type, PC, PW type all are to adopt rainproof, the PVC coaming plate wind-proof of prefabricated board, does not all have from taking out function.A kind of preferably is ZRF type (2000YJ205) in Henan Province's " house kitchen toilet fume centralized exhausting duct " atlas, it adopts prefabricated component to be assembled into the suction type blast cap, can flashing, wind proofing, and can make by wind-force and produce negative pressure in the flue system, thereby reach from the effect of taking out.But it still underuses the external force effect of wind-force, and resistance ratios is bigger.
Three. summary of the invention:
At the deficiencies in the prior art and defective, the purpose of this utility model provides a kind of pneumatic type blast cap, it not only can flashing, wind proofing, and can also make full use of the natural wind effect, make and produce more powerful negative pressure in the ducting system, reach more effective, reduce the resistance of fume exhauster discharging from taking out function.
For finishing above-mentioned task, the utility model has adopted following technical scheme: the pneumatic type blast cap is mainly by base, cross flabellum, wormwheel blade, top cover, axis is formed, base end face is the flange plate type circle that has four through holes, the base vertical component is the cylinder of both ends open, be provided with a cross bracing frame on cylinder bore top, the bracing frame center has the through hole that size matches with middle shaft diameter, the center that axis vertically is positioned over base is through in the through hole of bracing frame and fixes with screw, cross flabellum is arranged on the inner chamber top of the cylinder of a both ends open, the internal diameter of this cylinder is a bit larger tham the external diameter of base cylinder, the center of cross flabellum has a through hole that matches with middle shaft diameter, cross flabellum is enclosed within and places on the base on the axis, connect by bearing, the top cover that is enclosed within the axis top is for circular, the centre has the through hole that matches with axis, connect with bearing, wormwheel blade is the rectangular thin slice of a series of arcs, they are connected with top cover and cross flabellum respectively at two ends up and down, and rounded being distributed in forms arranging of an air vane chip between top cover and the cross flabellum.
In order to guarantee the intensity of wormwheel blade, blade strikes out the W type and strengthens stressed rib.
Base can be cylinder iron or engineering plastics make, the cross flabellum can be made of PVC plastics and other material, wormwheel blade can be made of aluminium or other lighter anti-aging material.
The utility model is contained in the exit opening place of vertical flue gas emission, no matter any direction has wind, the wormwheel blade structure of similar windmill can be rotated automatically by the effect of exogenous wind power, drives the cross flabellum and rotates thereupon, make to produce negative pressure in the system, thereby in flue, form from taking out operating mode.This design is very reasonable, and very ingenious, with the past be that the blast cap of windproof and rain proof is compared, its superiority is self-evident, the ZRF type blast cap ratio of forming with prefabricated component, the outstanding advantage of the utility model on function, plurality of advantages such as light in addition, convenient, practical, attractive in appearance.The utility model will provide solid technical foundation for carrying out 99 years No. 295 literary compositions of nation-building portion, contribute for optimizing urban environment, and its economic benefit and social benefit all will be huge.
The utility model not only can be used for the exit of the vertical flue gas emission in lavatory, kitchen, can also be used in other vertical air channel, flue outlet place.
Four. description of drawings:
Accompanying drawing 1 is a pneumatic type cap structure schematic diagram
Accompanying drawing 2 is a pneumatic type blast cap A-A generalized section
The Reference numeral division is as follows: 1-base; 2-wormwheel blade; 3-cross flabellum; 4-axis; 5-top cover; 6-bearing; 7-screw; The through hole of 8-firm banking; The outer cylinder of 9-cross flabellum; Cross supporting frame on 10-base
Five. the specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail: base 1 bottom surface has fixing with through hole 8, cross bracing frame 10 is arranged at base vertical cylinder top, axis 4 is through in the hole at base support frame center, fixing with screw 7, cross flabellum 3 is arranged at cylinder 9 inner chamber tops, its central through hole is through on the axis 4, be put on the base 1, combine by bearing 6, a lid 5 is fixed on axis 4 tops, connect with bearing, wormwheel blade 2 rounded being placed between top cover 5 and the cross flabellum 3 form arranging of an air vane chip, resemble a drum from the appearance, resemble a windmill again, space between its blade and the blade, the wind that any direction is blown can both rotate it, thereby drives cross flabellum 3 rotations, produce negative pressure, form from the operating mode of taking out.
